Mounting fitting for a lightweight panel

ABSTRACT

The invention relates to a mounting fitting ( 1 ) for anchoring in a honeycomb panel ( 15 ). The mounting fitting ( 1 ) has an adhesive channel ( 6 ) and adhesive discharge openings ( 8 ). The invention proposes to arrange the adhesive discharge openings ( 8 ) in such a way that they are located in a cover panel ( 16 ) of the honeycomb panel ( 15 ) and to construct the mounting fitting ( 1 ) with an adhesive distribution groove ( 9 ) running like a screw-thread around the periphery, into which the adhesive discharge openings ( 8 ) open. It is thus ensured that there is good distribution of adhesive and that the hole ( 18 ) in the cover panel ( 16 ) of the honeycomb panel ( 15 ) is completely filled with adhesive. Adhesive discharged on the inner side of the cover panel ( 16 ) improves adhesion.

The invention relates to a mounting fitting for a lightweight panelhaving the features of the preamble of claim 1. The invention relatesalso to an arrangement having such a mounting fitting and to a method ofbonding the mounting fitting in place, having the features of thepreambles of claims 13 and 14.

A “lightweight panel” is to be understood as being a panel having twocover panels which are joined by a core of low mechanical strength. Thecore can be, for example, a foam or can be a honeycomb; the latter caseis referred to as a honeycomb panel. Honeycomb panels are used, forexample, in the manufacture of furniture and need to be joined to oneanother or to other components. The mechanical strength of the core isnot sufficient for a stable anchoring. Any reference to a honeycombpanel hereinbelow is to be understood as also including a lightweightpanel generally.

WO 2006/106131 A1 discloses a mounting fitting for a lightweight panelreferred to as a “connection insert”. The known mounting fitting has akind of hollow bolt having a head and a sleeve arranged on the hollowbolt. The internal diameter of the sleeve is larger than the externaldiameter of the hollow bolt so that an annular gap is formed. Themounting fitting is inserted into a lightweight panel through a hole ina cover panel of the lightweight panel until the head is located insidethe cover panel and ends flush therewith. Adhesive is then introducedinto the hollow bolt, the adhesive being discharged from the hollow boltthrough radial openings and entering the annular gap between the sleeveand the hollow bolt. The adhesive becomes distributed in the annular gapand is discharged at both ends of the sleeve, so that it joins themounting fitting on inner sides to the cover panels of the lightweightpanel. The hollow bolt of the known mounting fitting also has dischargeopenings in its head through which adhesive is discharged into the holein the one cover panel of the lightweight panel and bonds the head tothe cover panel. The mounting fitting which has been inserted into thelightweight panel and bonded to its cover panels forms a fixing pointfor the connection of the lightweight panel to another component.

The problem of the present invention is to propose a mounting fittingfor a lightweight panel having improved distribution of adhesive.

That problem is solved according to the invention by the features ofclaim 1. The mounting fitting according to the invention having thefeatures of claim 1 has an adhesive channel in its interior having anadhesive filling opening at one end face of the mounting fitting andhaving at least one adhesive discharge opening close to the one end faceat one side, that is to say on the periphery, of the mounting fitting.Close to the end face of the mounting fitting at which the adhesivefilling opening is located means that the adhesive discharge opening isarranged on the mounting fitting at a location that is preferably insideone of the two cover panels of a lightweight panel when the mountingfitting has been inserted into the lightweight panel in the intendedway. Adhesive introduced into the adhesive channel of the mountingfitting is discharged in a hole in the cover panel of the lightweightpanel into which the mounting fitting has been inserted.

Furthermore, the mounting fitting according to the invention has on itsouter side an adhesive distribution groove into which the adhesivedischarge opening opens. The adhesive distribution groove runs in such away that adhesive entering it from the adhesive discharge opening isdistributed in the peripheral direction and in the longitudinaldirection. For example, the adhesive distribution groove can havegrooves running in the longitudinal and peripheral directions andcrossing one another like a lattice. One construction in accordance withthe invention provides an adhesive distribution groove running like ascrew-thread around the periphery. The adhesive distribution groove isarranged in a region of the mounting fitting that is located in thecover panel of a lightweight panel when the mounting fitting has beeninserted into the lightweight panel in the intended way. The adhesivedistribution groove can extend further over the length of the mountingfitting, that is to say into a region of the mounting fitting that islocated between the cover panels of a lightweight panel when themounting fitting has been inserted into the lightweight panel in theintended way. Adhesive discharged from the adhesive discharge opening(s)flows in the adhesive distribution groove, which is surrounded andcovered by the wall of the hole in the cover panel of the lightweightpanel into which the mounting fitting has been inserted, and thusbecomes distributed in the hole in the cover panel. In addition, theadhesive is discharged from the adhesive distribution groove on theinner side of the cover panel. By means of the adhesive distributiongroove according to the invention, it is possible for the annular gapsurrounding the mounting fitting in the hole in the cover panel to befilled completely with adhesive, so that a good full-surface bondcapable of bearing high mechanical stress is achieved. The adhesive thatis also discharged on the inner side of the cover panel bonds themounting fitting to the cover panel at that location and whereapplicable to the core or the honeycomb of the lightweight panel, sothat the strength of the bond between the mounting fitting and thelightweight panel is further increased. “Like a screw-thread” is to beunderstood as meaning that the adhesive distribution groove runs in theperipheral direction and in the longitudinal direction of the mountingfitting in order to distribute the adhesive both in the peripheraldirection and in the axial direction in the hole in the cover panel.“Like a screw-thread” does not necessarily mean that the adhesivedistribution groove has a constant pitch.

An advantage of the invention is the good distribution of the adhesivein the hole in the cover panel of the lightweight panel into which themounting fitting has been inserted, and on the inner side of the coverpanel.

In a preferred construction in accordance with the invention, theadhesive distribution groove is closed at the one end face of themounting fitting having the adhesive filling opening. “Closed” meansthat the adhesive distribution groove does not end in an opening at theone end face of the mounting fitting. The adhesive distribution groovecan end a short distance before the one end face of the mountingfitting; the mounting fitting can also have a radially outwardlyprojecting flange by means of which the adhesive distribution groove isclosed. By means of the flange, the mounting fitting is seated on theouter side of the cover panel of the lightweight panel into which themounting fitting has been inserted. The closed end of the adhesivedistribution groove prevents or at least reduces discharge of adhesiveat the one end face of the mounting fitting having the adhesive fillingopening. The adhesive therefore flows in the other direction and isdischarged, as desired, on the inner side of the cover panel of thelightweight panel. Discharge of adhesive on the outer side of the coverpanel is avoided or at least reduced.

In a further preferred construction in accordance with the invention,the adhesive distribution groove has a large free cross-sectional areain relation to the total cross-sectional area, the total cross-sectionalarea being understood as the cross-section up to the groove depth of theadhesive distribution groove. The large free cross-sectional area of theadhesive distribution groove reduces the flow resistance of the adhesiveand enlarges the contact area with the wall of the hole in the coverpanel, that is to say the area of the adhesive distribution groove thatis open on the outer side of the mounting fitting.

For bonding the mounting fitting to the other cover panel of thelightweight panel, one construction in accordance with the inventionprovides one or more discharge openings at the other end face of themounting fitting. The “other end face” is to be understood as being theend face of the mounting fitting remote from the end face having theadhesive filling opening. For discharge of adhesive, the other end facecan be open or can have openings and/or the adhesive discharge openingsare provided at the side, that is to say in the periphery of themounting fitting, at or close to the other end face. By virtue of thatconstruction in accordance with the invention, the mounting fitting isbonded to both cover panels of the lightweight panel and its mechanicalhold in the lightweight panel is further improved. There is no need toprepare the other cover panel of the lightweight panel; to insert themounting fitting it is necessary merely to make a hole in one coverpanel of the lightweight panel.

One construction in accordance with the invention provides adisplaceable extension piece for the mounting fitting. The extensionpiece can be, for example, in the form of a sleeve and arranged on themounting fitting or, conversely, the mounting fitting can be in the formof a sleeve and the extension piece can be arranged therein. Theextension piece has an adhesive channel which communicates with theadhesive channel of the mounting fitting. That is to say, adhesiveintroduced into the mounting fitting through the adhesive fillingopening not only is discharged into the adhesive distribution groovefrom the adhesive discharge opening(s) of the mounting fitting, but alsooverflows from the mounting fitting into the displaceable extensionpiece. From the extension piece, the adhesive is discharged through oneor more adhesive discharge openings arranged at an end face remote fromthe adhesive filling opening of the mounting fitting and/or at one sideof the extension piece close to the end face of the extension pieceremote from the adhesive filling opening of the mounting fitting. Themounting fitting is inserted into a hole in a cover panel in alightweight panel with the extension piece extended, that is to say withthe extension piece increasing the length of the mounting fitting. Theextension piece strikes the inner side of the other cover panel. Themounting fitting is introduced further into the lightweight panel untilit ends flush with the one cover panel or is seated by its flange on thecover panel, the mounting fitting being displaced along the extensionpiece so that the mounting fitting is automatically adapted to thethickness of the lightweight panel. The adhesive then introduced isdischarged, as described above, in the region of the one cover panel. Inaddition, the adhesive is discharged from the adhesive dischargeopening(s) of the extension piece at the inner side of the other coverpanel and bonds the mounting fitting to that cover panel also. Themounting fitting is thus bonded to both cover panels of the lightweightpanel.

One construction in accordance with the invention provides a throughflow throttle in the adhesive channel of the mounting fitting or itsextension piece. The throughflow throttle is especially a change incross-section, for example an aperture plate in the adhesive channel.The throughflow throttle brings about damming of the introduced adhesivein order that a sufficient amount of adhesive is discharged from theadhesive discharge opening(s) of the mounting fitting into the adhesivedistribution groove.

In a preferred construction in accordance with the invention, themounting fitting is cylindrical, i.e. has a cylindrical outer surface,and is thus matched to a cylindrical drilled hole in the cover panel ofthe lightweight panel. A cylindrical shape or a cylindrical envelope inthe region of the one cover panel of the lightweight panel may besufficient.

In a preferred construction in accordance with the invention, theadhesive channel is constructed to serve simultaneously as a screwchannel for the introduction of a screw. That means, in particular, astraight construction of the adhesive channel having an adequatecross-section. The cross-section of the adhesive channel can be largerthan the thread diameter of the screw, so that the screw is not directlyin engagement with the mounting fitting, but indirectly by way of theadhesive introduced into the mounting fitting. Instead of a screw it isalso possible for a different, pin-like element to be introduced intothe mounting fitting as anchor. The screw can be understood generally asbeing an element having an external thread.

In one construction in accordance with the invention, the mountingfitting can be reduced in length to match different thicknesses oflightweight panel. That is possible, for example, by means of thedisplaceable extension piece of the mounting fitting which has alreadybeen described. Another possibility is a crushable or crumplableconstruction of the mounting fitting. The mounting fitting can beresiliently and/or plastically deformable; it can have a bellows-like orconcertina-like construction at least over a part of its length. Alattice-like, preferably diagonal or lozenge-shaped construction, of awall portion of the mounting fitting is also possible for the purpose ofits being reducible in length. That has the additional advantage thatthe holes of the lattice-like peripheral wall can form adhesivedischarge openings. One construction in accordance with the inventionprovides one or more folding elements which, to reduce the length of themounting fitting, fold outwards or inwards when the mounting fittingstrikes the inner side of the other cover panel of the lightweight panelwith the folding elements. With the mentioned possible length-reducingmethods, the mounting fitting can also be of one-piece construction.

In the method according to the invention, a mounting fitting accordingto the invention, especially of the kind described above, is insertedinto a lightweight panel through a hole in a cover panel of thelightweight panel and adhesive is introduced through the adhesivefilling opening at one end face of the mounting fitting. The adhesive isdischarged through the adhesive discharge openings and bonds themounting fitting to at least one, preferably both, of the two coverpanels of the lightweight panel. After the adhesive has hardened, ascrew or generally an element having an external thread is screwed,without pre-drilling, into the adhesive channel of the mounting fitting.The screw or the element having an external thread enables anothercomponent to be joined to the lightweight panel. A screw or an elementhaving an external thread can be screwed into the adhesive channel ofthe mounting fitting, that is to say it is in engagement with themounting fitting. A fixing made exclusively by means of the adhesive inthe adhesive channel, without direct thread engagement between the screwor generally the element having an external thread and the mountingfitting, is also possible, in which case the mounting fitting serveschiefly for distribution of the adhesive while the effective loads thatarise are transmitted to the honeycomb panel predominantly by the screwby way of the adhesive.

The invention relates also to an arrangement of a mounting fitting ofthe kind described above which has been inserted into a lightweightpanel and bonded to one or preferably both of the cover panels thereofin the way described.

The invention is described in greater detail below on the basis ofexemplary embodiments shown in the drawing:

FIG. 1 is an axial section through a mounting fitting according to theinvention;

FIG. 2 is a perspective view of the mounting fitting shown in FIG. 1;and

FIG. 3 is an axial section through a second embodiment of the invention.

The mounting fitting 1 according to the invention shown in FIGS. 1 and 2has a first part 2 and an extension piece 3. The first part 2 and/or theextension piece 3 can be made, for example, by injection-moulding fromplastics material. Hereinbelow, the term mounting fitting 1 refers tothe first part 2 or alternatively to the first part 2 and the extensionpiece 3.

The first part 2 of the mounting fitting 1 according to the inventiontakes the form of a cylindrical sleeve having an outwardly projectingradial flange 4 at one end face 5. The interior of the tubular firstpart 2 forms an adhesive channel 6 the mouth of which at the one endface 5 of the first part 2 forms an adhesive filling opening 7 of themounting fitting 1. Just underneath the radial flange 4, that is to sayclose to the one end face 5, the first part 2 has adhesive dischargeopenings 8 which pass through its wall. In the exemplary embodiment ofthe invention shown and described, the first part 2 has two adhesivedischarge openings 8 which are arranged opposite one another. The numberand arrangement of the adhesive discharge openings 8 is not essential tothe invention, however. On its outer side, the first part 2 has anadhesive distribution groove 9 running like a screw-thread around theperiphery, which extends from the radial flange 4 over about ⅔ of thelength of the first part 2. At the one end face 5 of the first part 2having the adhesive filling opening 7, the adhesive distribution groove9 is closed by the radial flange 4. The adhesive discharge openings 8open into the adhesive distribution groove 9.

The extension piece 3 is likewise a sleeve-like part which isdisplaceable in the sleeve-like first part 2 of the mounting fitting 1.The interior of the tubular extension piece 3 forms an adhesive channel10 which communicates with the adhesive channel 6 of the first part 2;the adhesive channels 6, 10 of the first part 2 and the extension piece3 merge into one another. The extension piece 3 has an aperture plate asthroughflow throttle 11 in its adhesive channel 10. The mouth of theadhesive channel 10 at the end face of the extension piece 3 remote fromthe radial flange 4 forms an adhesive discharge opening 12. The end faceof the extension piece 3 has arcs which can also be understood asadhesive discharge openings 13. Between the concave arcs, the end edgeof the extension piece 3 forms feet 14.

As shown in FIG. 1, the mounting fitting 1 according to the invention isprovided for anchoring in a lightweight panel, for example, as shown, ina honeycomb panel 15. The honeycomb panel 15 has two cover panels 16between which there is honeycomb 17 which joins the two cover panels 16.

For insertion of the mounting fitting 1, a hole 18 is drilled in the onecover panel 16 and where applicable the honeycomb 17 below the hole 18is destroyed. Prior to insertion into the honeycomb panel 15, themounting fitting 1 has been fully extended, that is to say the extensionpiece 3 has been moved out of the first part 2 by the maximum amount.The mounting fitting 1 is inserted, extension piece 3 first, through thehole 18 into the honeycomb panel 15, the extension piece 3 striking theother cover panel 16 of the honeycomb panel 15. The first part 2 of themounting fitting 1 is introduced into the honeycomb panel 15 to a depthsuch that the radial flange 4 is seated on the outer side of the onecover panel 16, the extension piece 3, which is in contact with theinner side of the other cover panel 16, moving into the first part 2.The mounting fitting 1 thus adapts itself automatically to the thicknessof the honeycomb panel 15. If a raised portion, caused by the radialflange 4, on the one cover panel 16 of the honeycomb panel 15 isundesirable, the mounting fitting 1 can also be configured without theradial flange 4 (not shown) and can be introduced into the honeycombpanel 15 to end flush with the outer side of the one cover panel 16.

After insertion into the honeycomb panel 15, the adhesive distributiongroove 9 is located in the hole 18 in the one cover panel 16 of thehoneycomb panel 15. The adhesive distribution groove 9 extends furtherinto the intermediate space between the two cover panels 16.

Using a device not shown, adhesive is introduced under pressure throughthe adhesive filling opening 7 into the mounting fitting 1 which hasbeen inserted into the honeycomb panel 15. The adhesive becomesdistributed in the adhesive channel 6 and is discharged through theadhesive discharge openings 8 into the adhesive distribution groove 9.The adhesive flows through the adhesive distribution groove 9 and thusbecomes distributed over the periphery and in the axial or longitudinaldirection in the hole 18 in the one cover panel 16. The hole 18 in thecover panel 16 surrounding the mounting fitting 1 is filled completelyby the adhesive. In addition, adhesive is discharged on the inner sideof the cover panel 16 and at that location too bonds the mountingfitting 1 to the cover panel 16. The adhesive is discharged from theadhesive channel 6 of the first part into the adhesive channel 10 of theextension piece 3, flows through the throughflow throttle 11 and isdischarged from the adhesive discharge openings 12, 13 of the extensionpiece 3. At the end face of the extension piece 3 it becomes distributedon the inner side of the other cover panel 16 of the honeycomb panel 15and thus bonds the mounting fitting 1 also to the other cover panel 16,so that the mounting fitting 1 is firmly bonded to both cover panels 16of the honeycomb panel 15. The aperture plate forming the throughflowthrottle 11 brings about damming of the adhesive and ensures that asufficient amount of adhesive flows under sufficient pressure throughthe adhesive discharge openings 8 of the first part 2 of the mountingfitting 1 into the adhesive distribution groove 9 and further in theadhesive distribution groove 9, so that the adhesive becomes distributedin the hole 18 in the cover panel 16. It is thus ensured that the hole18 is completely filled with adhesive and that adhesive is discharged onthe inner side of the one cover panel 16.

In accordance with an embodiment of the invention, a screw (not shown inthe drawing) or some other element having an external thread is screwed,without pre-drilling, through the adhesive filling opening 7 into theadhesive channel 6, 10 of the mounting fitting 1 when the adhesive hashardened. Since the extension piece 3 of the mounting fitting 1 consistsof plastics material, the screw can pass through the aperture plateforming the throughflow throttle 11. The adhesive channel 6, 10 thussimultaneously forms a screw channel. The screw enables a component (notshown) to be joined to the honeycomb panel 15. The thread of the screwcan be, but not need not be, in engagement with the mounting fitting 1.

The adhesive distribution groove 9 has steep groove flanks which end ina blade-like but blunt edge 19. The groove base 20 is rounded, so thatthe adhesive distribution groove 9 is wide also in the region of thegroove base 20. The adhesive distribution groove 9 thus has a large freecross-sectional area and consequently a low flow resistance for theadhesive. The open area of the adhesive distribution groove 9 facing thewall of the hole 18 in the cover panel 16 of the honeycomb panel 15 isalso large.

In the subsequent description of the mounting fitting 1 shown in FIG. 3,essentially only the differences with respect to the mounting fitting 1shown in FIGS. 1 and 2 are described and, in addition, to explain FIG. 3reference is made to the descriptions of FIGS. 1 and 2. In FIG. 3,corresponding components have been given the same reference numerals asin FIG. 1.

Unlike the mounting fitting 1 shown in FIGS. 1 and 2, the mountingfitting 1 shown in FIG. 3 is in one piece; it does not have adisplaceable extension piece. For adapting to different thicknesses ofhoneycomb panel 15, the mounting fitting 1 shown in FIG. 3 can bereduced in length. Its feet 14 are in the form of folding elements 21which, in the un-deformed starting position, are directly obliquelyinwards. The un-deformed starting position is shown by dotted lines inFIG. 3. The folding elements 21 are integral with a wall of the mountingfitting 1 via a folding site or folding line 22. The folding line 22 isformed by a peripheral groove 23 on the outer side of the mountingfitting 1 and a concave peripheral edge 24 on the inner side of themounting fitting 1. If the mounting fitting 1 is introduced into thehoneycomb panel 15 and its feet 14, formed as folding elements 21,strike the inner side of the other cover panel 16, as a result of theirobliquely inwardly oriented alignment the feet fold inwards along thefolding line 22 into the position shown by solid lines in FIG. 3. Inprinciple, it is also possible for the feet 14 to fold outwards in orderto reduce the length of the mounting fitting 1 for adapting to differentthicknesses of honeycomb panel 15.

As in FIGS. 1 and 2, the mounting fitting 1 shown in FIG. 3 is asleeve-like part having an adhesive channel 6, an adhesive fillingopening 7 at one end face 5 of the mounting fitting 1 and an apertureplate as throughflow throttle 11 approximately in the longitudinalcentre of the adhesive channel 6.

Likewise in accordance with FIGS. 1 and 2, the mounting fitting 1 shownin FIG. 3 has, close to its one end having the adhesive filling opening7, adhesive discharge openings 8 which open into a helical adhesivedistribution groove 9. When the mounting fitting 1 has been insertedinto the honeycomb panel 5, the adhesive discharge openings 8 arelocated in a hole 18 in the one cover panel 16 of the honeycomb panel15. The mounting fitting 1 shown in FIG. 3 has more adhesive dischargeopenings 8 that open into the adhesive distribution groove 9 than doesthe mounting fitting 1 shown in FIGS. 1 and 2.

The mounting fitting 1 shown in FIG. 3 does not have a flange at its endface; it is inserted into the honeycomb panel 15 to end flush with theouter side of the one cover panel 16 of the honeycomb panel 15. Theadhesive distribution groove 9 is closed at one end face 5 of themounting fitting 1, so that no adhesive, or at least very littleadhesive, is discharged at that location. The adhesive thus becomesdistributed in the hole 18 in the one cover panel 16 of the honeycombpanel 15 and flows onto the inner side of the cover panel 16.

The mounting fitting 1 shown in FIG. 3 otherwise corresponds to themounting fitting 1 shown in FIGS. 1 and 2 and to avoid repetitionreference is made to the descriptions of FIGS. 1 and 2.
